Definitions

  • the present invention generally relates to electrical connection boxes in which an internal circuit is constituted by a wire and pressing contact terminals brought into pressing contact with the wire and more particularly, to an electrical connection box in which heat dissipation of a wire connected to external electrical heating elements such as a relay and a fuse is facilitated such that quantity of electric current flowing through the wire is increased.
  • connection box An example of a known connection box is disclosed in EP-A-0 044 636.
  • a wire W is laid on an insulating plate 3 disposed in a casing of the electrical connection box, which is constituted by an upper casing 1 and a lower casing 2 and pressing contact terminals 5 and 6 are brought into pressing contact with the wire W.
  • a tab 5a of the pressing contact terminal 5, which acts as an input-output terminal portion, is projected out of a terminal hole formed on a bottom wall of a fuse receiver 1a protruding from an upper face of the upper casing 1 and is connected, as shown in Fig. 2, to a terminal 8 of a fuse 7, which is fitted into a bore of the fuse receiver la.
  • a relay receiver and a connector receiver are provided on the upper face of the upper casing 1 and tabs 6a of tabs 6 brought into pressing contact with the wire W are projected into the relay receiver and the connector receiver so as to be connected to relays and contact bonding terminals connected to electric devices.
  • an electrically operative portion a of the wire W which is interposed between the pressing contact terminals 5 and 6 at input and output sides, respectively, is set to a shortest distance, while an electrically inoperative portion b of the wire W other than the electrically operative portion a is cut off in the vicinity of spots of connection between the wire W and the pressing contact terminals 5 and 6 such that the wire W is shortened.
  • an object of the present invention is to provide, with a view to eliminating the above mentioned drawbacks of conventional electrical connection boxes, an electrical connection box in which by facilitating heat dissipation of a wire connected, via pressing contact terminals, to external electrical heating elements such as a relay and a fuse, not only a large quantity of electric current can flow through the wire but rise of temperature of interior of the electrical connection box is restrained.
  • EP-A-0 703 117 which forms prior art pursuant to Article 54 (3) EPC, discloses an electrical connection box including an internal circuit in which a plurality of pressing contact terminals are brought into pressing contact with a wire and input-output terminal portions of the pressing contact terminals are connected to external circuits, respectively;
  • the electrical connection box according to the invention has the further feature that the electrically inoperative portion forms a loop at the first pressing contact terminal.
  • Fig. 4 shows an internal circuit of an electrical connection box K3 according to the present invention.
  • a wire is laid in the same manner as prior art of Fig. 1. Therefore, laying of the wire in the electrical connection box is described with reference to Fig. 1, hereinafter.
  • Pressing contact terminals 5 and 6 are connected, through pressing contact, to a wire W laid preliminarily on an insulating plate 3 so as to form the internal circuit.
  • the insulating plate 3 preliminarily assembled with the wire W and the pressing contact terminals 5 and 6 is accommodated in an upper casing 1 and a lower casing 2 such that the electrical connection box K3 is assembled.
  • the tab 6a of the pressing contact terminal 6, which acts as the input-output terminal portion of the pressing contact terminal 6, is formed into a flat platelike shape and is inserted into a terminal receiving slit of a connector so as to be connected to a contact bonding terminal contact bonded to a distal end of a wire.
  • the pressing contact terminal 6 mainly functions as a pressing contact terminal at an output side.
  • the tab 5a of the pressing contact terminal 5 is folded down into a U-shaped form and a terminal receiving groove 5c extends from an upper end of the tab 5a downwardly and a terminal 8 of a fuse 7 or a terminal of a relay (not shown) is inserted into the terminal receiving groove 5c so as to be connected to the pressing contact terminal.
  • the pressing contact terminal 5 mainly functions as a pressing contact terminal at an input side.
  • a pressing contact terminal 5' which is connected to the terminal 8 of the fuse 7 has two pressing contact portions, i.e., first and second pressing contact portions 5b' and 5d'.
  • first and second pressing contact portions 5b' and 5d' One of the first and second pressing contact portion 5b' and 5d' is brought into pressing contact with an electrically operative portion a, while the other of the first and second pressing contact portion 5b' and 5d' is brought into pressing contact with an electrically inoperative portion b.
  • the first pressing contact portion 5b' extends continuously from a lower portion of a tab 5a' of the pressing contact terminal 5' and the second pressing contact portion 5d' is bent orthogonally from the first pressing contact portion 5b'.
  • Slots 5e' and 5f' are, respectively, formed at the first and second pressing contact portions 5b' and 5d' and a pressing contact blade is, in turn, formed at a periphery edge of each of the slots 5e' and 5f'.
  • the electrically inoperative portion b is extended from the electrically operative portion a. As shown in Fig. 5, the electrically inoperative portion b is curved arcuately and a distal end of the electrically inoperative portion b is brought into pressing contact with the first pressing contact portion 5b'.
  • the electrically operative portion b can be laid orthogonally to the second pressing contact portion 5d' for the electrically operative portion a, the electrically operative portion b can be provided without interfering with the electrically operative portion a.
